Well see that is the problem with communication via serializations: I
was trying to interpret what you were thinking and got it wrong. You
see I assumed that because you were (in that case) discussing both RDF
and XML in the same paragraph that you were talking about both. I
looking back over this I now see that I was wrong.
But this is a big point in our whole discussion ... the more precise we
can be in our communication the better we can understand what the other
person intends. Sometimes that means *not* allowing the receiver to
make willy nilly assumptions and interpretations about what the sender
is sending. Communication implies *some level* of shared semantics.
Shared semantics on the web might mean qualifying our terms (words)
with URIs to the receiver can GET some information about what the
sender is trying to say.
On the other hand it might also point out the fact that the receiver
needs to have a working parser :-)
